Warm-Season Mesoscale Convective Processes: A Tribute to Lance

Virtually all areas of meteorology have been touched by the work of Lance Bosart.   Just one of many topics he has delved into – mesoscale convective processes – includes a vast range of phenomena: extreme rainfall events, mesoscale aspects of tropical cyclones, the diurnal cycle of rainfall, mesoscale convective systems, derechos, MCVs, dryline convection, tornadic thunderstorms, monsoon precipitation systems, and the coupling of convection with high-amplitude gravity waves.  Unlike any other, he has the ability to tease out key physical processes almost exclusively from operational data.  One important subject of Lance’s research is reviewed here: the surface impacts of high-amplitude convectively coupled dynamical systems.
